摘　　要：针对厂级300MW供热机组,建立了高背压供热、抽凝供热、低压缸切除供热以及电锅炉补偿供热4种供热方式的数学模型,分析了其供热能力和能耗水平。为优化热电厂内多台供热机组热电负荷分配,建立了热电联产机组能耗分析模型,并基于鸟群优化算法得到了不同供热负荷需求下的最佳分配方案。结果表明:当供热负荷为400MW时,单机组高背压供热的煤耗量最低;当供热负荷为600MW时,两台机组高背压组合模式供热煤耗量最低;当供热负荷为800MW时,高背压和低压缸切除组合模式供热煤耗量最低;当热负荷为1000MW时,高背压和电锅炉-低压缸切除组合模式供热煤耗量最低。The mathematical models of high back pressure heating,condensate pumping heating,low pressure cylinder cutting heating and electric boiler compensation heating are established for 300MW plant heating unit,and their heating capacity and energy consumption are analyzed.To enhance the efficiency of distributing heat and power load across multiple heating units within a thermal power plant,an energy consumption analysis model for cogeneration units is developed.The optimal distribution scheme is then determined using the bird optimization algorithm,considering various heating load requirements.The findings indicate that at a heating load of 400MW,the high back pressure heating unit exhibits the lowest coal consumption.When the heating load is 600MW,the combined heating coal consumption of the two units with high back pressure is the lowest.When the heating load is 800MW,the combined model of high back pressure and low pressure cylinder removal has the lowest heating coal consumption.When the heat load is 1000MW,the coal consumption of high back pressure and electric boiler-low pressure cylinder excision combined mode is the lowest.
